Flexible blind of the roller type



April 4, 1939. A. VALERI FLEXIBLE BLIND OF THE ROLLER TYPE Filed Feb. 6, 1937 Patented Apr. 4, 1939 UNITED STATES FLEXIBLE BLIND THE ROILER TYPE Alfredo Valerl, Bragado, Argentina Application February 6, 1937, Serial No. 124,358 In Argentina November 21, 1936 2 Claims.

This invention relates to a metal flexible blind oi the roller type, applicable to any aperture in lieu of the known Venetian blinds.

It is characterized in that the slats are connected by their sides to a series of links in such a manner that all of the said slats may be rolled up on a roller or drums mounted at the top in a suitable way. Consequently, the links constitute at each side a chain moving within fluted guides, these links being equipped with leather washers to muffle the noise caused by the lateral frictions.

In order that the invention may be clearly understood and readily put into practice it is by way of example illustrated in the accompanying drawing wherein:

Fig. 1 is a front view of the flexible blind, the guides thereof being shown in section to enhance the understanding of the drawing,

Fig. 2 is a section along line A--B,

Fig. 3 is a vertical section along line C--D,

Fig. 4 is a vertical section along line EF,

Fig. 5 is a lateral diagrammatic view of the flexible blind,

Fig. 6 shows one of the slats provided with a sight, and

Fig. 7 is a section through this latter slat.

In the various figures of the drawing like visible parts are indicated by like reference numerals.

The structure in accordance with the model shown consists of the two guides I located at the sides and having a fluted cross-section and which suitably fit in with the jambs or the aperture to which the flexible blind is to be applied.

n the otherhand, the slats 2 which may have any known cross-section have their lateral portions provided with the wings 2' thereby to engage the slits of the links 3. Each secondwing 2' is slightly bent into the shape of a Z (Fig. 3)

was to ensure its connection with the said links I (not shown in the drawing).

In passing through the holes 1 this cable 6 becomes fettered and thus keeps the slats 2 spaced apart one from another.

One or more of the slats 2 may be equipped with an aperture 8 (Figs. 6 and '7) having a lid 8 At the top a roller ll (Fig. or a series of 5 drums of a known type, either with or without springs to facilitate the wrapping-up, is mounted in a convenient manner so as to roll up the flexible blind for the purpose of lifting it with a view to wholly or partially disclose the aperture it covers. 1

The flexible blind according to Fig. 1 may have a .stop constituted by the two cross rods l2 provided at their extreme ends with rubber heels l3 which brush over the guides I whereas the near ends are united by an antagonistic spring It the influence of which causes the rubber heels l3 to rest with acertain energy on the. guides l. Spring. I4 is'enclosed within a box IE having two hooked handles l6 which issue therefrom and are operated with a view to displace the rods I 2 in the act of lifting or lowering the flexible blind. By this means it is feasible to fasten the blind at whatever height may be considered to be the fittest.

A gripping loop I! is provided to allow of lifting or lowering the Venetian by the aid of a rod or stick in case its height should be without the reach of the hand.

The working will be understood from the foregoing explanations.

As the flexible blind is rolled up by known means the links 3 turn on their shafts 4 and carry along with them the slats 2 which are then being placed in their corresponding sequence.

The washers 5 travel along the guides I muiiling the noise owing to their being made from leather or some other resilient material.

It will be appreciated how little space is necessary for this flexible blind, the same being superior to such blinds as are constituted by wings, for not only need these latter space ahead of them for 40 opening but also are they exposed to the action of the wind which'will shake them unless they be secured by special means.

It is obvious that certain constructional detail modifications may be introduced without thereby departing from the scope of the present invention which is clearly ascertained in the appended claiming clauses.

What I claim is:

1. A flexible blind of the roller type comprising a series of metal slats each of which is provided at both ends with a plate-like projection, a pair of chains supporting the ends of said slats, said chains having pivoted links provided with slots receiving said plate-like slat projections,

whereby said slats are non-rotatably mounted in said links, discs of sound-deadening material mounted on the pivots of said links and having "a diameter greater than the width of the links, a

channel shaped guide at each lateral edge of the blind in which said chains and discs operate, and a roller on which the slats and chains may be rolled. a

2. A flexible blind of the roller type comprising a series of slats each of which is provided at both ends with a plate-like projection, a pair 01' chains memo VALERI.
